This map represents the area of Vietnam and the locations of both soil cores and vegetation samples included in the Coastal Carbon Atlas.
Total Carbon stock estimates were calculated for each geography in total, and for mangrove, tidal marsh, and seagrass habitats, when available.
We estimate that Vietnam contains a mean estimate of 59310000 megagrams per hectare sediment carbon stock.
We estimate that Vietnam contains between 68170000 to 50450000 megagrams per hectare sediment carbon to a depth of 1 m, with a mean estimate of 59310000 megagrams per hectare.
| Country | Territory | Total Stocks | Upper CI | Lower CI |
|---|---|---|---|---|
| Vietnam | Vietnam | 59310000 | 50450000 | 68170000 |
| Country | Territory | Habitat | Total Stock | Lower CI | Upper CI | Standard Error |
|---|---|---|---|---|---|---|
| Vietnam | Vietnam | Mangrove | 58970000 | 50200000 | 67740000 | 4568000 |
This total estimate includes total mangrove soil carbon stocks, with a mean estimate of 58970000 megagrams per hectare soil carbon to a depth of 1 meter.
| Country | Territory | Habitat | Total Stock | Lower CI | Upper CI | Standard Error |
|---|---|---|---|---|---|---|
| Vietnam | Vietnam | Marsh | 345100 | 252000 | 438300 | 48530 |
This total estimate also includes total tidal marsh carbon stocks, with a mean estimate of 345100 megagrams per hectare soil carbon to a depth of 1 meter.
| Territory | Habitat | Total Stock |
|---|---|---|
| Vietnam | Seagrass | 1700000 |
This estimate also includes seagrass soil carbon stocks for Vietnam which we estimate to have a mean of 1700000 megagrams per hectare sediment carbon stock.
We estimate mangrove area in Vietnam to be 186000 to 245500 hectares, with a mean estimate of 211800 hectares according to Global Mangrove Watch, Bunting et al. (2018).
We estimate tidal marsh area in Vietnam to be 819.8 to 1530 hectares, with a mean estimate of 1354 according to Worthington et al. (2024).
We estimate seagrass area to be Vietnam to be a mean of 15740 hectares, according to McKenzie et al. (2020), which aggregates global seagrass data from a number of sources.
This section of the report details whether data is available to estimate Tier I, Tier II, or Tier III value estimates for tidal marsh, mangrove, and seagrass ecosystems in Vietnam.
If data for the selected country is available in the Coastal Carbon Atlas, we have applied a Tier II emission factor based on a simple average of country specific data queried from the Atlas.
Within the Coastal Carbon Atlas, data from the selected geography, Vietnam, includes soil samples, but does not yet include vegetation samples.
Soil core data from Vietnam included in the Coastal Carbon Atlas consists of 184 soil profiles from 42 sites. This data comes from 1 distinct habitat type(s).
In the case that there is not yet any country specific information in the Coastal Carbon Atlas, we instead applied IPCC Tier I estimate, which are estimated global values. IPCC Global estimates for mangrove, marsh, and seagrass ecosystems are listed below.
The table titled “Availiability of Territory-Level Data” in this section also details whether the calculated Tier II, or territory-level sediment carbon stock value is significantly different from the estimated global values. This is observed in the “Reporting Insight” column, and can be helpful in observing when a habitat has a higher or lower estimated sediment carbon stock value than the IPCC Global estimates.
| Habitat | Mean | Lower_CI | Upper_CI |
|---|---|---|---|
| mangrove | 386 | 351 | 424 |
| marsh | 255 | 254 | 297 |
| seagrass | 108 | 84 | 139 |
| Country | Territory | Habitat | Tier | Reporting Insight |
|---|---|---|---|---|
| Vietnam | Vietnam | mangrove | Territory-Level | Territory-level average is significantly less than global value |
| Vietnam | Vietnam | marsh | Global | No Tier II data available at this time |
| Vietnam | Vietnam | seagrass | Global | No Tier II data available at this time |
This section includes estimated global sediment carbon stocks included for Vietnam. In the case that all habitats; mangrove, tidal marsh, and seagrass have availiable territory-level estimates, please refer to Table 2: IPCC Tier I Value Estimates for applicable global values.
This table includes country or territory level sediment carbon stock estimates for Vietnam. Estimates in this table were derived from available soil core data queried from the Coastal Carbon Atlas.
A selected country may have available territory-level values for one or multiple habitats, this is dependent on core data accessible through the Coastal Carbon Atlas. If a territory has habitat area, but that respective habitat type does not have an associated territory-level stock estimate, there is insufficient core data in the Coastal Carbon Atlas to estimate sediment carbon stock. At the time of analysis, referencing Version 1.5.0 of the Coastal Carbon Atlas and Data Library, Vietnam is represented by a total of 184 cores across 1 distinct habitats.
| Country | Territory | Habitat | Mean Stock (MgHa) | Lower CI | Upper CI | Standard Error |
|---|---|---|---|---|---|---|
| Vietnam | Vietnam | mangrove | 278 | 262 | 294 | 8.14 |
Tier III: modeled sediment carbon stocks were estimated, when available, using remote sensing data from Maxwell et al 2021 and Sanderman et al 2018. The table below details whether estimated values are available for any habitat in Vietnam, and details any overlap with associated global or territory-level estimates.
If there are no modeled estimates associated with the selected geography and specific habitat of interest, please refer to above tables of global and territory-level sediment carbon stocks.
| Country | Territory | Habitat | Mean Stock (MgHa) | Lower CI | Upper CI |
|---|---|---|---|---|---|
| Vietnam | Vietnam | mangrove | 262 | 220 | 304 |
In the selected geography, modeled estimated stock MgHa values are, less than territory-level values estimated from Coastal Carbon Atlas Data. In this case, the modeled Remote-sensing esimate overlaps country-specific average. Additionally, estimated modeled stock values derived from remote sensing are less than estimates global IPCC values. In this case, the modeled Remote-sensing esimate is significantly less than Tier I global estimates.
